Furthermore, it is easy to manufacture a molded product with a complicated uneven shape. In particular, the spacer can be located on the outer side of the divided shell mold and the inner side of the outer shell mold, so that The shell mold combined with the split shell mold and the outer shell mold is strongly integrated. In particular, the thermal expansion coefficient of the inner shell mold is slightly the same as that of the outer shell mold, and the thermal expansion coefficient of the spacer is larger than that of the inner and outer shell molds. Therefore, the difference in thermal expansion rate can be used to improve the physical properties of the inner shell mold and the outer shell mold during heating molding. Furthermore, the integrity of the shell mold after the mold is cooled can be reduced. As a result, the molded product can be easily taken out.

In FIG. 2, the forming die 4 has a shell mold 1 and a bottom mold. Mold 2 and upper mold 3. As shown in Fig. 3, 'Shell mold 1 has a guide mold for the outer mold and a pair of divided shell molds 7a, 7b for the inner mold. The guide mold 8 is composed of no adhesive part. Made of a single mold material, the guide mold 8 has a rectangular second through hole. A protective film is formed on the inner peripheral surface of the second through hole to prevent the molding material from adhering to the upper one. A pair of divided shell molds 7a, 7b is the first with a l-shaped cross section! The divided shell mold 7a and the second divided shell mold 7b are combined with each other in the horizontal direction. The combined divided shell molds 7a, 7b are inserted into the second through hole of the guide mold 8. One of the pair of divided shell molds 7a, 7b is formed with a through hole through which a molding material can be inserted, and has an inner periphery for forming an outer peripheral surface of the V-shaped groove array. The lower mold 2 is inserted into the lower end of the shell mold 1 and fixed. The lower die 2 has an inner surface for forming an upper side of the V-groove array. The upper mold 2 is inserted from the upper end of the shell mold 1 and can be slidably arranged in the shell mold 1. The upper mold 3 has an inner surface for forming a bottom surface of the V-groove array.

Description of the invention (7) Lower the upper mold 3, press the sintered frit 5 and shape it. The formed glass or mold is then cooled. The formed article is then taken out of the mold. By performing in this manner, a glass molded product was obtained. In this forming process, when the sintered glass frit 5 is heated and pressurized, the sintered glass frit 5 is in a softened or melted state. In this state, the pressing force is transmitted to the inner shell molds 7a, 7b and the outer shell mold 8 through the glass material. That is, the shell mold 8 has a mechanically strong structure and can resist pressure. When the shell mold 8 is made of a single mold material without an adhesive portion, a strong mold that can resist the aforementioned pressure can be obtained. When the molded product is taken out from the mold, first, the upper mold 3 is removed from the mold 4. Then, the shell mold 8 is removed from the mold 4. The first divided shell mold 7a is divided by the second divided shell mold 7b. The molded article is then separated by the divided shell molds 7a, 7b. After this, the molded product can be taken out from the mold. With the above configuration, the sintered frit 5 is heated and press-molded, and when the molded product is in close contact with the inner surface of the shell mold 1, the shell mold 1 can be individually decomposed into the i-th divided shell mold 7a and the second divided shell mold 7b And guide mode 8. Therefore, the molded product is not damaged, and the molded product can be easily taken out. In particular, when the molded product is a V-groove array as shown in Fig. 1 and is a rectangular shaped body having a step 6a and a V-groove 6b, the molded body is likely to adhere to the shell mold 1 easily. This is because the sintered glass frit 5 must be spread over minute portions of the ridge line portion and the corner portion of the forming gap (cavity) of the forming mold 4. For this purpose, the mold is filled with sintered glass 5 having a volume slightly larger than the volume of the V-shaped groove after forming. Therefore, when the upper mold 3 is lowered and pressurized on the sintered frit 5, the excess sintered frit 5 can be allowed to enter between the shell mold 1 and the upper mold 3, and the paper size is suitable for financial and family scale (CNS) A4 specifications ( 21GX297 mm) " --- -10- (Please read the precautions on the back before filling in the page) • Binding line 524781 X- Φ Printed A7 B7 'Invention Note (8) ) Or, the contact portion between the shell mold 1 and the lower mold 2 causes burrs. When this phenomenon occurs, the molded article in the mold is likely to adhere to the shell mold 1. However, when such a burr is produced, the mold 4 of this embodiment can also be used to easily remove the molded product from the mold. In addition, the burr of the formed product obtained during the forming is thin and brittle. Therefore, when the molded product is taken out from the pair of divided shell molds 7a, 7b, all the burrs are bent and removed. After the burr is bent, a tapered portion can be formed at the burr. This eliminates the need for an additional step of removing burrs. Furthermore, there is no need for another step of forming a tapered portion on the molded product. The pair of divided shell molds 7a, 7b and the guide mold 8 are preferably made of a hard material which is harder than the molded product. For example, a hard material such as a tungsten carbide alloy can be used. This prevents the mold from being damaged when a large pressure is generated during press molding. Furthermore, the life of the mold can be extended. Furthermore, the carbonized alloy has a wealth heat temperature south of iron ', so that a material with a high melting temperature can be formed. [Embodiment 2] Fig. 4 is a sectional view of a shell mold 1 of a forming mold according to another embodiment of the present invention. In Fig. 4, the shell mold 1 has a pair of divided shell molds 7a, 7b forming a pair of inner shell molds, a guide mold 8 and a spacer 9 of the outer mold. A spacer 9 is provided between the divided shell molds 7 a and 7 b and the guide mold 8. The other structure of the mold of the second embodiment is the same as that of the first embodiment. The split shell molds 7a, 7b and the guide mold 8 are preferably made of a hard material which is harder than the molded product. Further, the separator 9 should have a hardness ratio of the divided shell mold 7a, and the paper size is applicable to the Chinese national standard (〇 奶) 8 4 specifications (21〇 '^ < 297 mm :) II equipment-I ~ ~ order III line ( (Please read the notes on the back before filling out this page) -11-V. Description of the invention (9) 7b is still soft. Furthermore, it is desirable that the spacer 9 has a thermal expansion coefficient larger than that of the pair of divided shell mold cores 7b. With this configuration, the combined shell molds i can be further and more strongly cured. When the material used to constitute the split shell molds 7a, 7b and the guide mold 8 is a tungsten carbide alloy, in order to insert the split shell molds 7a, 7b into the guide mold 8, it must be formed between the guide mold 8 and the split shell molds 7a, 7b. A little gap. Due to the existence of the gap, the divided molds 7 a and 7 b are shaken in the guide mold 8 instead. In order to eliminate this shaking phenomenon, a spacer 9 made of stainless steel, which is softer than other materials, is provided between the divided shell molds 7a, 7b and the guide mold 8 to further strengthen the shell mold. The materials for the divided shell molds 7a, 7b and the guide mold 8 are preferably made of a tungsten carbide alloy or the like. Further, the material of the spacer 9 should be made of stainless steel. At this time, the thermal expansion coefficient of the stainless steel used to form the spacer 9 is 150 × 10-7, and the thermal expansion coefficient of the superhard alloy used to form the divided shell molds 7a, 7b and the guide mold 8 is 56 × 1 (Γ7. That is, isolation Part 9 has a coefficient of thermal expansion approximately three times greater than that of the split shell mold 7a, Gui and guide mold 8. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, the thermal expansion coefficient of the partition 9 is greater than that of the split shell mold 7a, Gui and guide. For the structure with large thermal expansion coefficient of the mold 8, firstly, the divided shell molds 7a, 7b and the spacer 9 are inserted into the guide mold 8 at normal temperature. At this time, the thickness of the spacer 9 is slightly smaller than the predetermined thickness. Therefore, a small gap is formed between the divided shell molds 7a, 7b and the spacer 9 and the guide mold 8. Thereby, the operation of combining the divided shell molds 7a, 7b and the spacer 9 in the guide mold 8 becomes easy. Furthermore, the combination The subsequent mold or the molding material in the mold is heated to expand the spacer 9 between the divided shell molds 7a, 7b and the guide mold 8. Since the thermal expansion of the spacer 9 is larger than that of the divided shell molds 7a, 7b and the guide mold 8, The gap can be reduced, and the paper size applies the Chinese National Standard (CNS) A 4 specifications (2I0X297 mm) 524781
